Van Horstmann's Specullum This tiny mirror bangs around the wearer's neck and has the ability to reflect back the fighting qualities of an enemy.
When the wearer fights a challenge he can 'swap his base Strength, Toughness, Initiative and Attacks values with his enemy. He has the choice of not using the mirror, but if he does he must swap all characteristics for the duration of the challenge. So the wearer fights with his enemy's S, T, I and A whilst his enemy fights with the wearer's S. T, I and A.
